Subject: [Intel-gfx] [PATCH] drm/i915: nuke local versions of WARN_ON/WARN_ON_ONCE
Date: Fri, 21 Jan 2022 15:29:57 +0200	[thread overview]
Message-ID: <20220121132957.3778555-1-jani.nikula@intel.com> (raw)

In general, we should avoid redefining kernel macros like this. It can
get confusing, and what gets used will depend on whether the header is
included or not. Moreover, we should prefer drm_WARN_ON() and
drm_WARN_ON_ONCE() anyway, which include the stringified error condition
in the message.
